d6c5f97c13 Test suite overhaul + fixes for the three bugs it uncovered (#441)
* ci: run the whole test tree and make the plugin-safety job assert something real

The unit-tests CI job ran an explicit 24-file allowlist that had rotted:
63 of 90 test files (display, vegas, store manager, web API, web_interface)
never ran on a PR. The job now runs all of test/ (minus test/plugins, which
the plugin-safety job owns) so new test files are enrolled by default and
any exclusion needs a visible, commented --ignore.

The plugin-safety job was a green no-op: plugins/ is empty in CI, so every
test skipped with 'Manifest not found'. It now renders a bundled
deterministic fixture plugin (test/fixtures/plugins/ci-fixture-plugin,
golden images included for all 8 default sizes) via LEDMATRIX_PLUGINS_DIR,
and sets LEDMATRIX_REQUIRE_PLUGINS=1 so discovering zero plugins fails
loudly instead of skipping green. The per-plugin suites document that they
target dev machines with real plugins installed.

Coverage is now measured and enforced in exactly one place — the CI
unit-tests step (--cov=src --cov=web_interface --cov-fail-under=45, from a
measured 47% baseline). pytest.ini previously declared --cov-fail-under=30
but CI always passed --no-cov, so the gate had never run anywhere; local
pytest is now coverage-free and fast.

Enabling the 63 unenrolled files surfaced three cases of test rot, fixed
here: test_display_controller_vegas_tick.py could not collect without the
hardware rgbmatrix module (now uses the emulator convention), the
state-reconciliation unrecoverable-cache tests broke when production added
the is_plugin_uninstalled tombstone check (bare Mock returned truthy),
and test_get_system_status assumed the optional psutil dependency
(now installed via requirements-test.txt and guarded by importorskip).

* test: replace can't-fail tests with real assertions

test_font_manager.py was 5 of 6 tests shaped as 'try: call(); assert True /
except: assert True' — running in CI while unable to fail on any
regression. Rewritten against the real FontManager API and the bundled
assets/fonts: returned font types, cache-hit identity, distinct entries per
size, default-font fallback for unknown families and corrupt files
(recorded in failed_loads), BDF native-size reading, text measurement, and
cache lifecycle.

test_display_manager.py's test_draw_text ended in 'assert True'; it now
renders onto a known-black canvas and asserts pixels were actually lit —
which required un-breaking the fixture's freetype MagicMock so draw_text's
isinstance check doesn't silently swallow the draw.

test_display_controller.py carried a permanently-skipped test whose skip
reason already declared it redundant; deleted.

Both display test files now set EMULATOR=true before importing
display_manager (the same convention as test_display_dirty_tracking.py) so
they collect standalone instead of depending on which test module imports
display_manager first.

* test: cover the untested fragile logic (compatibility gate, secrets, config merges, durations, skin cards)

New unit tests for pure or filesystem-only logic that previously had zero
direct coverage:

- test_compatibility.py: the semver install gate (parse_semver suffix
  handling, every range operator, TRUSTWORTHY_FLOOR behavior for cores
  reporting untrustworthy versions, 'more restrictive wins', and the
  malformed-manifest shapes that used to raise).
- test/web_interface/test_secret_helpers.py: the canonical x-secret
  helpers — find/separate/mask/remove, array-item secrets, no input
  mutation, and a separate->recombine round-trip.
- test/web_interface/test_api_v3_helpers.py: the module-level helpers
  behind the plugin config save endpoint (_is_plugin_update_available,
  _coerce_to_bool including the int==1 quirk, deep_merge including its
  shared-subtree shallowness, _parse_form_value, dotted-key-aware
  _get_schema_property/_set_nested_value).
- test_base_plugin_duration.py: get_display_duration's full coercion
  ladder (instance attr -> config -> 15.0), including the bool-is-int
  quirk where display_duration=True means one second.
- test_config_manager_secrets.py: the secrets round-trip — deep-merge on
  load, strip on save, group pruning, the load fast path — and two
  characterized sharp edges marked SUSPECTED BUG: an unreadable secrets
  file at save time writes secrets into config.json in plaintext, and a
  same-mtime-same-size content swap is served stale.
- test_schema_manager_merge.py: merge_with_defaults branch behavior (None
  replacement vs falsey preservation, dict-vs-scalar mismatches, arrays
  replaced wholesale, defaults never mutated).
- test_skin_system.py (extended): render_skin_card shares _render_game's
  3-strike counter but never resets it on success — the asymmetry is
  pinned in both directions, along with card fallthrough and the disable
  interaction between the two paths.

Suspected bugs are characterized, not fixed — each carries a comment so a
future behavior change is deliberate rather than accidental.

* test: add drift guards for cross-file contracts

Three guard suites that pin contracts spanning multiple files, where one
side changing unilaterally breaks the other silently:

- test_version_comparison_consistency.py: the repo's four version
  comparators (compatibility.parse_semver, api_v3's packaging-based
  _is_plugin_update_available, store_manager update_plugin's raw string
  equality, skin_runtime._major) answer differently on the same inputs.
  A table pins each one's verdict; update_plugin is driven through its
  real code path to show the SUSPECTED BUGs: 'v1.2.0' vs '1.2.0'
  triggers a full reinstall the UI calls unnecessary, and a locally-ahead
  plugin gets downgraded. A pairwise-ordering check keeps parse_semver
  agreeing with packaging on plain X.Y.Z.
- test/web_interface/test_secret_separation_parity.py: api_v3.py carries
  three inline copies of find_secret_fields/separate_secrets that lack
  the canonical module's array-item support. The copy count is asserted
  exact (it may only go down; new copies must import
  src/web_interface/secret_helpers), the missing-array-support gap is
  asserted so it can't grow silently, and the canonical behavior that
  migration will adopt is documented executably.
- test_discovery_path_contract.py: the three 'where is plugin X'
  resolvers (PluginManager discovery, StoreManager._find_plugin_path,
  SchemaManager.get_schema_path) agree on the configured directory, and
  their divergent fallback chains are characterized. Also pins the
  .standalone-backup- naming contract shared by store rollback and
  discovery, and _resolve_skin_target's path-traversal rejection.

* test: address review feedback — fixture lifecycle, test names, ClassVar

- ci-fixture-plugin: call display_manager.clear() before rendering (per
  plugin guidelines — the fixture should model a well-behaved plugin),
  add a class docstring, and document why Pillow is deliberately not
  pinned in its requirements.txt (core dependency; harness installs
  nothing).
- Rename two tests whose names contradicted their assertions:
  test_unparseable_core_version_is_compatible ->
  test_unparseable_core_with_high_floor_is_blocked, and
  test_unreadable_secrets_file... -> test_corrupt_secrets_file...
- Annotate TestGetSchemaProperty.SCHEMA as ClassVar (RUF012).

* fix: unify version comparison, refuse secret-leaking saves, reset skin strikes on card success

Fixes the three suspected bugs this PR's characterization tests pinned,
flipping those tests to assert the corrected behavior:

- plugins/store: ONE shared update comparator. New
  compatibility.is_update_available() (PEP 440 via packaging) is now used
  by both the web UI's update badge (api_v3._is_plugin_update_available
  is a thin alias) and store_manager.update_plugin's reinstall decision.
  Previously update_plugin used raw string equality: 'v1.2.0' vs '1.2.0'
  triggered a full reinstall the UI called unnecessary, and a locally-
  ahead plugin (2.0.0 installed, registry 1.9.0) was silently DOWNGRADED.
  Now equivalent spellings skip the reinstall and locally-ahead versions
  are never downgraded; unparseable versions still reconcile by
  reinstalling from the registry.

- config: save_config and save_config_atomic now refuse (ConfigError)
  when config_secrets.json exists but cannot be loaded. Both previously
  proceeded without stripping, writing the merged secrets into
  config.json in plaintext. The shared _load_secrets_for_save() helper
  raises with an actionable message instead; a missing secrets file is
  still fine (nothing to strip), and _migrate_config's catch-all keeps
  boot resilient.

- skins: render_skin_card resets _skin_failures on both success paths
  (vegas card returned, or mode renderer handled), mirroring
  _render_game. Transient card failures no longer accumulate across a
  session until they permanently disable a working skin.

* fix: harden shared comparator edges from review

- is_update_available: reject truthy non-string versions (a malformed
  manifest can carry a number; packaging raises TypeError on those) by
  surfacing the mismatch instead of raising.
- store_manager.update_plugin: drop the truthiness gate around the
  comparator so a missing version on either side follows the shared
  'no update' verdict, keeping the store consistent with the UI badge;
  a missing manifest still uses the reinstall recovery path.
- config_manager._load_secrets_for_save: catch only expected read/parse
  failures (OSError/ValueError/RecursionError) so implementation bugs
  propagate as themselves, and log with traceback.

Running the Web Interface

Standalone (Development)

From the project root:

python3 web_interface/start.py

Or using the shell script:

./web_interface/run.sh

As a Service (Production)

The web interface can run as a systemd service that starts automatically based on the web_display_autostart configuration setting:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web  # Start on boot

Accessing the Interface

Once running, access the web interface at:

Configuration

The web interface reads configuration from:

  • config/config.json - Main configuration
  • config/config_secrets.json - API keys and secrets

API Documentation

The V3 API is mounted at /api/v3/ (app.py:144). For the complete list and request/response formats, see docs/REST_API_REFERENCE.md. Quick reference for the most common endpoints:

Configuration

  • GET /api/v3/config/main - Get main configuration
  • POST /api/v3/config/main - Save main configuration
  • GET /api/v3/config/secrets - Get secrets configuration
  • POST /api/v3/config/raw/main - Save raw main config (Config Editor)
  • POST /api/v3/config/raw/secrets - Save raw secrets

Display & System Control

  • GET /api/v3/system/status - System status
  • POST /api/v3/system/action - Control display (action body: start_display, stop_display, restart_display_service, restart_web_service, git_pull, reboot_system, shutdown_system, enable_autostart, disable_autostart)
  • GET /api/v3/display/current - Current display frame
  • GET /api/v3/display/on-demand/status - On-demand status
  • POST /api/v3/display/on-demand/start - Trigger on-demand display
  • POST /api/v3/display/on-demand/stop - Clear on-demand

Plugins

  • GET /api/v3/plugins/installed - List installed plugins
  • GET /api/v3/plugins/config?plugin_id=<id> - Get plugin config
  • POST /api/v3/plugins/config - Update plugin configuration
  • GET /api/v3/plugins/schema?plugin_id=<id> - Get plugin schema
  • POST /api/v3/plugins/toggle - Enable/disable plugin
  • POST /api/v3/plugins/install - Install from registry
  • POST /api/v3/plugins/install-from-url - Install from GitHub URL
  • POST /api/v3/plugins/uninstall - Uninstall plugin
  • POST /api/v3/plugins/update - Update plugin

Plugin Store

  • GET /api/v3/plugins/store/list - List available registry plugins
  • GET /api/v3/plugins/store/github-status - GitHub authentication status
  • POST /api/v3/plugins/store/refresh - Refresh registry from GitHub

Real-time Streams (SSE)

SSE stream endpoints are defined directly on the Flask app (app.py:607-619 — includes the CSRF exemption and rate-limit hookup alongside the three route definitions), not on the api_v3 blueprint:

  • GET /api/v3/stream/stats - System statistics stream
  • GET /api/v3/stream/display - Display preview stream
  • GET /api/v3/stream/logs - Service logs stream

Development

When making changes to the web interface:

  1. Edit files in this directory
  2. Test changes by running python3 web_interface/start.py
  3. Restart the service if running: sudo systemctl restart ledmatrix-web

Notes

  • Templates and static files use the v3/ prefix to allow for future versions
  • The interface uses Flask blueprints for modular organization
  • SSE streams provide real-time updates without polling
